Description

詳細な説明Detailed explanation

本発明は、金属片を溶接して部材を製造する方法に関するものであり、金属片間に少なくとも１つの材料片を配置して溶接する。また、本発明は、本部材の使用に関するものである。 The present invention relates to a method of manufacturing a member by welding metal pieces, and at least one material piece is arranged between the metal pieces and welded. The present invention also relates to the use of the present member.

互いに固定された少なくとも２つの異なる材料を含む材料構成物は、自動車、商用車、バスまたは鉄道車両などの輸送機関製造分野においてますます重要になってきている。いわゆる「複合材料構造」において、常に適切な材料を適切な場所に適用する必要がある。しかしながら、従来の接合方法では、鋼をアルミニウムに接合する、あるいは鋼を炭素繊維に接合するといった異種材料の接合組合せにおいて限界に達している。他にも、使用する材料の腐食電位が異なるという問題がある。薄板または要素の間に直接的な接触がある場合、卑材料に腐食が起きるおそれがある。塩化物のように湿潤部分または溶解液がある場合、問題はさらに深刻になる。 Material constructs containing at least two different materials fixed to each other are becoming increasingly important in the field of transportation manufacturing such as automobiles, commercial vehicles, buses or rail vehicles. In the so-called "composite structure", it is always necessary to apply the right material to the right place. However, in the conventional joining method, the limit is reached in the joining combination of different materials such as joining steel to aluminum or joining steel to carbon fiber. Another problem is that the corrosion potentials of the materials used are different. If there is direct contact between the sheet steel or the elements, the base material may corrode. The problem is exacerbated when there is a wet area or solution, such as chloride.

英国特許第1363536号は、パネル平面から貫入するたくさんのタブを全タブがパネルシートの平面に立った状態で使用する結合体に適用されパネルの厚さの総計よりも厚さ寸法が大きい構造用パネルについて記載している。さらに、タブは相互に取付け可能なため、２枚の薄板間に延びる１対の中間タブ間の結合が強固である。英国特許第1363536号は、パネルの強度を高めるためにパネルシートに対するタブの垂直位置および穿孔に関連して形成される一対のタブを示している。当該構造では、パネル層を２枚だけ相互に結合させている。 UK Pat. No. 1363536 applies to joints that use many tabs penetrating from the panel plane with all tabs standing on the plane of the panel sheet, for structures that are thicker than the total thickness of the panel. Describes the panel. Further, since the tabs are interchangeable, the bond between the pair of intermediate tabs extending between the two thin plates is strong. British Patent No. 1363536 indicates a pair of tabs formed in connection with the vertical position of the tabs with respect to the panel sheet and perforations to increase the strength of the panel. In this structure, only two panel layers are bonded to each other.

本発明の目的は、従来技術における問題点を解消し、互いに溶接される金属片間に少なくとも１つの材料片が配置された溶接部材の製造方法を達成することである。また、本発明は、上記部材の使用を目的とする。本発明の基本的な特徴は、添付の本願特許請求の範囲に記載する。 An object of the present invention is to solve a problem in the prior art and to achieve a method for manufacturing a welded member in which at least one material piece is arranged between metal pieces to be welded to each other. Moreover, this invention aims at use of the said member. The basic features of the present invention are described in the appended claims.

本発明によると、互いに溶接される金属片の少なくとも一方に、少なくとも１つの突起部が設けられる。溶接される金属片間に配置される少なくとも１つの材料片に、少なくとも１つの開口部が設けられ、互いに溶接される金属片の一方の金属片の突起部の少なくとも一部分が、開口部を貫通する。これにより、突起部の上端を介して、溶接される他方の金属片と機械的に接触する。金属片の溶接は、溶接される第１の金属片の突起部に接続する第２の金属片の表面に対して溶接効果をもたらすことによって行う。 According to the present invention, at least one protrusion is provided on at least one of the metal pieces to be welded to each other. At least one piece of material placed between the pieces of metal to be welded is provided with at least one opening, and at least a portion of the protrusions of one piece of metal to be welded to each other penetrates the opening. .. This causes mechanical contact with the other piece of metal to be welded through the top edge of the protrusion. Welding of a metal piece is performed by providing a welding effect on the surface of the second metal piece connected to the protrusion of the first metal piece to be welded.

このように、本発明によって製造された部材において、互いに溶接される金属片の少なくとも一方に少なくとも１つの突起部が設けられ、突起部の上端によって、溶接される第２の金属片と機械的に接触する。本発明の説明において、用語「第１の金属片」とは突起部を有する金属片を指し、用語「第２の金属片」とは突起部の上端が機械的に接触するもう一方の金属片を指す。本発明の説明において、用語「突起部の上端」とは、溶接を行う前に一方の金属片に固定される突起部の端部とは反対側の突起部の端部を指す。本発明の一実施例において、両金属片に突起部が設けられ、一方の金属片の突起部は他方の金属片の突起部と向かい合っていない。 As described above, in the member manufactured by the present invention, at least one protrusion is provided on at least one of the metal pieces to be welded to each other, and the upper end of the protrusion mechanically matches the second metal piece to be welded. Contact. In the description of the present invention, the term "first metal piece" refers to a metal piece having a protrusion, and the term "second metal piece" is another metal piece with which the upper end of the protrusion mechanically contacts. Point to. In the description of the present invention, the term "upper end of the protrusion" refers to the end of the protrusion opposite to the end of the protrusion fixed to one metal piece before welding. In one embodiment of the present invention, both metal pieces are provided with protrusions, and the protrusions of one metal piece do not face the protrusions of the other metal piece.

少なくとも１つの開口部が設けられた材料片は、中間層として、溶接される金属片の間に配置されるものである。材料片の開口部は、互いに溶接される金属片の一方の突起部の少なくとも一部が貫通できる形状である。突起部は開口部に対して配置されるため、突起部と開口部との直接的な接触をすべて防止できる。よって、開口部を貫通する突起部の部分は、溶接される第２の金属片の表面に機械的に接続される。金属片が互いに上述のように配置される場合、本発明による溶接は、溶接される金属片の突起部に接触する金属片の表面に作用する溶接効果に重点を置いて行われる。これにより、溶接された金属片間に配された少なくとも１つの材料片で構成される積層溶接部材を達成できる。 The material piece provided with at least one opening is arranged as an intermediate layer between the metal pieces to be welded. The opening of the material piece is shaped so that at least a part of one protrusion of the metal pieces welded to each other can penetrate. Since the protrusion is arranged with respect to the opening, all direct contact between the protrusion and the opening can be prevented. Therefore, the portion of the protrusion penetrating the opening is mechanically connected to the surface of the second metal piece to be welded. When the metal pieces are arranged with each other as described above, the welding according to the present invention is performed with an emphasis on the welding effect acting on the surface of the metal pieces in contact with the protrusions of the metal pieces to be welded. This makes it possible to achieve a laminated welded member composed of at least one piece of material arranged between the welded metal pieces.

本発明によると、本発明の方法は２つの材料を互いに直接接触させることなく３部構成部材として接合できるため、直接互いに溶接できない少なくとも３つの部分からなる材料の組合せの接合が可能である。したがって、開口部を備えた材料片は、閉鎖法として、または適合接続法として他の薄板に接合され、溶接される金属片は相互に物質的に接続される。よって、中間層材料と溶接された金属片との間の腐食に対する異なる電気化学電位は、本発明の方法によって製造された部材に直接的に関連しない。 According to the present invention, since the method of the present invention can join two materials as a three-part component without directly contacting each other, it is possible to join a combination of materials consisting of at least three parts that cannot be directly welded to each other. Thus, the pieces of material with openings are joined to other sheet steels as a closure method or as a conforming connection method, and the metal pieces to be welded are materially connected to each other. Thus, the different electrochemical potentials for corrosion between the interlayer material and the welded metal pieces are not directly related to the members manufactured by the methods of the invention.

本発明により溶接される金属片は、被覆鋼、ステンレス鋼、アルミニウム、マグネシウム、銅または真鍮から作られる。金属片は同種の材料からなるか、あるいは金属片は互いに溶接可能な材料の組合せから形成される材料からなる。金属片を互いに溶接する場合、抵抗溶接法、TIGスポット溶接法、またはレーザビーム溶接もしくは電子ビーム溶接などのビーム溶接法などの熱接合法によって行う。互いに溶接される金属片の少なくとも一方に少なくとも１つの突起部が設けられ、この場合、金属片は少なくとも一部が立体的である。突起部の形状は、円錐形、ピン形、テーパ形または他の任意の表面形状であり、溶接される他方の金属片との機械的に接触するのに有用である。有利には、金属片には複数の突起部が設けられ、突起部は、射出成形、クリンチング、円錐絞り加工、発泡成形または液圧成形などの成形法によって製造される。 The metal pieces welded according to the present invention are made of coated steel, stainless steel, aluminum, magnesium, copper or brass. The metal pieces are made of the same type of material, or the metal pieces are made of a material formed from a combination of materials that are weldable to each other. When metal pieces are welded to each other, they are welded by a thermal joining method such as resistance welding, TIG spot welding, or beam welding such as laser beam welding or electron beam welding. At least one of the metal pieces to be welded to each other is provided with at least one protrusion, in which case the metal pieces are at least partially three-dimensional. The shape of the protrusions can be conical, pin-shaped, tapered or any other surface shape and is useful for mechanical contact with the other piece of metal to be welded. Advantageously, the metal piece is provided with a plurality of protrusions, which are manufactured by molding methods such as injection molding, clinching, conical drawing, foam molding or hydraulic molding.

溶接される金属片の間に中間層として配置される材料片は、被覆鋼、ステンレス鋼、アルミニウム、マグネシウム、銅もしくは真鍮など金属ベースの材料からなるか、または繊維複合体もしくはセメント板からなる。中間層には少なくとも１つの開口部が設けられ、開口部の位置は金属片の突起に対して決められるため、突起部の少なくとも一部分が開口部を貫通することができ、これにより、中間層材とのあらゆる機械的な接触が防止される。有利には、中間層は複数の開口部を有し、開口部は中間層を穿孔して形成できる。中間層の穿孔は、打抜き、押抜き、中抜き、切削、またはレーザビームあるいはプラズマジェットおよびプラズマビームなどの熱切断によって作製できる。 The piece of material placed as an intermediate layer between the pieces of metal to be welded consists of a metal-based material such as coated steel, stainless steel, aluminum, magnesium, copper or brass, or a fiber composite or cement plate. Since the intermediate layer is provided with at least one opening and the position of the opening is determined with respect to the protrusion of the metal piece, at least a part of the protrusion can penetrate the opening, thereby allowing the intermediate layer material. Any mechanical contact with is prevented. Advantageously, the intermediate layer has a plurality of openings, which can be formed by perforating the intermediate layer. The perforation of the intermediate layer can be made by punching, punching, hollowing, cutting, or thermal cutting such as laser beam or plasma jet and plasma beam.

本発明によると、突起部を備えた金属片は、中間層の開口部に積み重ねられる。中間層の開口部の領域は、突起部の少なくとも一部分が開口部を貫通する形状であり、これにより、積層時および積層後に、中間層、突起部および金属片の間に接触が生じない。積層を行う前に、中間層と突起部との接触を防止するために、絶縁材の層を中間層の表面に塗布する。絶縁材は重合体、流動性接着剤、接着テープ、フリース素材入りテープ、可塑性絶縁材またはセラミック材である。絶縁材は、溶接される金属片と中間層材との間の電気化学的絶縁、電解腐食および接触腐食が発生する危険性を回避する。積層時、開口部と突起部の位置関係から、中間層の形態は固定され、接合される。金属層を積層して溶接した後、中間層を所望の方法により金属片間に圧入して、溶接部材を得る。 According to the present invention, the metal pieces provided with the protrusions are stacked in the openings of the intermediate layer. The region of the opening of the intermediate layer is shaped so that at least a portion of the protrusion penetrates the opening so that no contact occurs between the intermediate layer, the protrusion and the metal pieces during and after lamination. Prior to laminating, a layer of insulating material is applied to the surface of the intermediate layer to prevent contact between the intermediate layer and the protrusions. The insulating material is a polymer, a fluid adhesive, an adhesive tape, a tape containing a fleece material, a plastic insulating material or a ceramic material. The insulating material avoids the risk of electrochemical insulation, electrolytic corrosion and contact corrosion between the metal pieces to be welded and the intermediate layer material. At the time of stacking, the form of the intermediate layer is fixed and joined due to the positional relationship between the opening and the protrusion. After laminating and welding the metal layers, the intermediate layer is press-fitted between the metal pieces by a desired method to obtain a welded member.
